Spatiotemporal electron-beam shaping is a bold frontier of electron microscopy. Over the past decade, shaping methods evolved from static phase plates to low-speed electrostatic and magnetostatic displays. Recently, a swift change of paradigm utilizing lig ...

AMER CHEMICAL SOC2022

Convergent beam electron diffraction (CBED) performed on two-dimensional (2D) materials recently emerged as a powerful tool to study structural and stacking defects, adsorbates, atomic 3D displacements in the layers, and the interlayer distances. The forma ...

Holographic reconstruction of interlayer distance of bilayer two-dimensional crystal samples from their convergent beam electron diffraction patterns

Tatiana Latychevskaia

Convergent beam electron diffraction (CBED) patterns of twisted bilayer samples exhibit interference patterns in their CBED spots. Such interference patterns can be treated as off-axis holograms and the phase of the scattered waves, and hence the interlaye ...

The past decade has witnessed a quantum revolution in the field of computation, communication and materials investigation. A similar revolution is also occurring for free-electron based techniques, where the classical treatment of a free electron as a poin ...

Controlling free electrons with optical whispering-gallery modes

Tobias Kippenberg

Free-electron beams are versatile probes of microscopic structure and composition(1,2), and have revolutionized atomic-scale imaging in several fields, from solid-state physics to structural biology(3). Over the past decade, the manipulation and interactio ...

NATURE PUBLISHING GROUP2020

Van der Waals heterostructures have been lately intensively studied because they offer a large variety of properties that can be controlled by selecting 2D materials and their sequence in the stack. The exact arrangement of the layers as well as the exact ...

Holographic imaging of electromagnetic fields via electron-light quantum interference

Fabrizio Carbone, Giovanni Maria Vanacore, Ivan Madan, Enrico Pomarico, Gabriele Berruto, Tatiana Latychevskaia, Tom Theodorus Antonius Lummen

Holography relies on the interference between a known reference and a signal of interest to reconstruct both the amplitude and the phase of that signal. With electrons, the extension of holography to the ultrafast time domain remains a challenge, although ...

American Association for the Advancement of Science (AAAS)2019

Electron Microscopy Investigation of Coated Multiwall Carbon Nanotubes Prepared by Reactive Ball Milling

László Forró, Endre Horvath, Jin Won Seo, Klara Hernadi

Homogeneous and stable inorganic coating of SiO2, Al2O3 and TiO2 was obtained on the surface of multiwall carbon nanotubes (MWNTs) by mechanically mixing them with precursor compounds in a planetary ball mill and by subsequent hydrolysis. Detailed studies ...

We propose and experimentally demonstrate a device in which common-path interferometry combined with off-axis holographic geometry is used to realize a digital holographic camera which can be attached to the camera port of a conventional transmission micro ...

Full field vertical scanning in short coherence digital holographic microscope

Christian Depeursinge, Christophe Moser, Etienne Cuche, Frédéric Montfort

In Digital holography Microscopes (DHM) implemented in the so-called "off axis" configuration, the object and reference wave fronts are not co-planar but form an angle of a few degrees. This results into two main drawbacks. First, the contrast of the inter ...
